It can be about anything you want, just don't slip into the deconstructionist bog, or I'll have to send somebody to get you out.
Interesting that several somewhat different interpretations have been posted. I was taught that anything you can find in good literature is valid, at least for you. Literature which is an obvious propaganda rant and does not allow this complexity and richness of interpretation is not great.
No worry here, not only will I not digress into some liberal interpretation I will also not provide my address for a flogging :-p
